Aristotle - Philosophy and Ethics
Aristotle was born in 384 BC in Stageira, Greece near today's Thessaloniki.
His father Nicomachus was a physician, so Aristotle got early contact with science and was well educated. He attended Plato's Academy at the age of eighteen and remained there for about twenty years. After Plato's Death, Aristotle travelled to the court of Hermias of Atarneus in Asia Minor, where he studied the botany and zoology of the island of Lesbos. In 343 BC, after his marriage with Pythias and the birth of his daughter Pythias, Aristotle was invited to become the tutor of Alexander the Great.
In 335 BC Aristotle returned to Athens to establish his own school which is known as the Lyceum. After the death of his wife Pythias, Aristotle married Herpyllis of Stageira who bore him a son named Nicomachus. Most of the today's well known works were written by Aristotle during the following period between 335 and 323 BC in Athens.
His most important works include topics of Logic, Physics, Metaphysics, Biology, Philosophy, Ethics, Politics, Rhetoric and Poetics. Aristotle studied almost every subject possible at his time. He was probably the last person to know everything there was to be known in his own time. Aristotle has been suspected to play a role in Alexander the Great's death but there's barely an evidence for that.
In 322 BC Aristotle died in Euboea of natural causes.
